Abstract
An enclosed shell is divided by a center plate and a pair of front and rear diaphragms which are disposed on the opposite sides of the center plate into four chambers. A center body is fitted over a valve body which internally houses a valve mechanism. The center body slides relative to the central portion of the center plate with a seal member interposed therebetween. The inner periphery of the front diaphragm is inserted inside the center body, and is held between the valve body and the center body at a location rearward of the seal member, whereby the overall length of the brake booster is reduced.
